Misled by Call Center

So Vodacom phoned me yesterday afternoon, they have listened to the recording and guess what, I am the guilty party (I suppose the client is always wrong hey, especially against the mighty Vodacom) apparently I did agree to this new contract although I still feel that I was misled by Vodacom and in my hart I know that I agreed to a contract where I will be paying less for my data (50% less) and not to be paying for 2 contracts at the end of day. Her suggestion to me was see if somebody can help me to pay this contract but cancellation is NOT option. If I want I can go to and Vodacom Shop and let they calculate what the penalty cost will be for early cancellation and to pay that to cancel the contract (once again more money). Where will I get the extra money from to pay an additional contract, all I wanted to do was to SAVE some money not spend more. Will Vodacom be in the red if they cancel this 1 contract, surely they will make up the money with the next person who is as uninformed as I was (I truly hope I was the last one) by taking a call from the Vodacom Call Center. I'm so desperate with my plea and I have not option as to take my make contact with Consumer Protection, I don't have the money to proceed with this contract , I just want to cancel this contract get this nightmare out of my life. Is happy customers not important for VODACOM?
